Hey i just got a pair of Veloflex Master 25's in the mail! im excited as they look so freaking cool!

Im a GP4000 user for the past 2 years, they are great tyres, but i wanted to try something different and then a friend tells me about this gum wall clinchers.

. Got a great deal at Ribble for a pair of velo and gp4000s.
Thought, i would put on some new GP4000 s's and let the veloflex cure a bit for added durability. Any of you know if this "curing" is real? I know tubs are cured, but curing clinchers?
Im debating about putting the velos or the gp4000s! (a delicious dilemma)
Also, talk about the master in 25 if you have experience, not much said about them, mostly i find talk about 23's
